Authors assessed the incidence of skin melanoma during outpatient consultations at the Consultation and Diagnostic Center of the Main Military Clinical Hospital named after academician N.N. Burdenko. During the period from 2019 to 2020, the authors diagnosed 68 patients with skin melanoma with stages ranging as follows: in situ ― 3 (4.4%) cases, stage IA ― 11 (16.2%) cases, IB ― 13 (19.1%) cases, IIA ― 11 (16.2%) cases, IIB ― 6 (8.8%) cases, IIC ― 9 (13.2%) cases, IIIA ― 3 (4.4%) cases, IIIB ― 4 (5.9%) cases, IIIC ― 3 (4.4%) cases, IV ― 5 (7.4%) cases. The necessity to apply the knowledge about the clinical and dermoscopic features of this malignant disease to diagnose skin melanoma, as well as exceptional prognostic significance of early detection of skin melanoma, were demonstrated.

Breast carcinoma is a heterogeneous group of tumors with a wide spectrum of clinical presentations, lesion characterization and diagnostic evaluation. Ductal carcinoma in situ accounts for 15%-20% of breast carcinomas detected in screened populations. Ductal carcinoma in situ has a variable appearance on mammography. The use of mammography has become as a very helpful tool for the early detection of larger number of patients with ductal carcinoma in situ and, thus, offering timely surgery and the need for the appropriate radiation treatment to patients. This study was undertaken as a hospital-based retrospective study to evaluate the varied spectrum of mammographic findings in 57 women with histopathological diagnosis of ductal carcinoma in situ. The spectrum of mammographic findings of ductal carcinoma in situ was found to vary widely. A thorough and vigilant inspection of a mammogram is necessary for all the patients to avoid the possibility of missing early diagnosis of this entity, since the findings are very subtle. Most cases show microcalcifications on mammograms and their early detection can help in early diagnosis, thereby offering conservative surgical approach to a patient. Microcalcifications can be present isolated or in association with a mass. These are mostly clustered in distribution followed by regional, segmental and ductal pattern of distribution. The morphology of microcalcifications is mostly amorphous, followed by pleiomorphic and fine heterogenous types. Hence, the mammogram must be interpreted with strict vigilance and proper attention to all aspects for early and correct diagnosis of ductal carcinoma in situ to help in proper guidance of its treatment.

Great importance in detecting cancer in the phase of in situ lays in the fact that the epithelial layer is deprived of blood and lymph vessels, so metastases may develop only when basal membrane has been broken. This paper includes 46 operated women in whom it preoperatively had been verified suspect non-palpable lesion. The preoperative diagnostics included use of high- resolution mammography, aimed mammography, palpatory examination, as well as fine-needle aspiration (FNA), biopsy and cytologic analysis of the sample. The methodology of this work implies the use of stereotaxic marking, specimen mammography and ex-tempore pathohistology analysis. Out of 46 investigated patients in clinical stage T0N0M0, in whom there were no signs of malignant disease, and according to suspect lesion of initial screening mammography, malignant lesions of breast tissue were diagnosed in 19 patients (41%) intraoperatively. Three of these lesions (15,8%) were histopathologically verified as in situ. Comparing our results with data of the Institute of oncology and radiology of Serbia hospital registry (IORS) for the year 2001, from 1173 patients registered with malignant lesions, only 16 ones (1,4%) had in situ cancer, operated on the basis of the suspect mammography of clinical stage T0N0M0. Statistically significant difference was found related to the number of detected cancers in this early phase of the breast malignant disease. This limits surgical intervention to tumorectomy, with preservation of the remaining breast tissue, what brings to healing, justifying in that way, screening examinations and routine application of the most contemporary diagnostic procedures.

Background: PReferentially expressed Antigen in MElanoma (PRAME) immunohistochemistry is increasingly used as diagnostic adjunct in the evaluation of melanocytic tumors. The expression and prognostic significance of PRAME in melanomas ≤1.0 mm and its diagnostic utility in the distinction from severely dysplastic compound nevi (SDN) have not been studied. Methods: We investigated and compared the immunohistochemical PRAME expression in 70 matched thin metastasizing and non-metastasizing melanomas and 45 nevi from patients with long-term follow-up (35 SDN and 10 unequivocally benign compound nevi). Results: Diffuse PRAME staining in >75% of lesional epidermal and dermal melanocytes identified 58.6% of thin melanomas but did not distinguish metastasizing from non-metastasizing melanomas (p = 0.81). A superficial atypical melanocytic proliferation of uncertain significance, in which the final diagnostic interpretation favored a SDN was the only nevus with diffuse PRAME expression (1/45). Melanomas and SDN with PRAME immunoreactivity exhibited different staining patterns. Most melanomas (67.6%) showed uniform PRAME expression in the in situ and invasive component, whereas most SDN (81.0%) showed a decreasing gradient with depth. Conclusion: Diffuse intraepidermal and dermal PRAME staining is highly specific for melanomas in the distinction from SDN. PRAME expression is not a prognostic biomarker in melanomas ≤1.0 mm.

Abstract Background Under diagnosis of COPD is serious problem in many countries world-wide because there are no generally detection tools available to detect high-risk patients for spirometry, and patients will not go for COPD check-up until a serious issue happens like exacerbation. Objective The aim of the work is trying to assess a new screening tool for early diagnosis of COPD. Patients and Methods The present study was conducted upon 500 subjects during the period from march 2018 to august 2018 who admitted to our chest department or visit our outpatient clinic, employees and visitors to Ain Sham hospitals.All subjects >40yrs who smoker or ex-smoker(≥10pack-years) applied a six variants(age,sex,packed years smoked during life ,dyspnea,chronic phlegmand chronic cohgh)questionnaire modified from PUMA questionnaire Subjects with score ≥5 did spirometry Results 500 subjects shared in the study 497 of them were males ( 99.4% )and 3 were females (.6%). 152of them(30.4%) had score <5 and 348 of them (69.6%)had score ≥5 who did spirometry.152 subjects did not perform spirometry. By spirometry we diagnosed 81(23.3) case COPD (fev1-fvc <.7) out of 348 subjects under gone spirometry and 16.2% of total subjects(500) . Conclusion Modified puma score is a simple and easy screening questionnaire for early detection of COPD cases and spirometry should be done to confirm the diagnosis or rule out.COPD is prevalent in many healthy apparent persons.

Numerous cells with very large and irregular nuclei (“monster” cells) have not hitherto been reported in desmoplastic melanoma (DM). Their prognostic significance in melanomas is a matter of debate, although some authors have associated them with more aggressive tumor behavior. We report a mixed DM on the scalp of an 88-year-old woman imitating an atypical fibroxanthoma. Tumor cells stained positive for SOX10, S100, and cyclin D1; BRAF mutation status was negative, and fluorescence in situ hybridization analysis showed copy number gains in 11q13 (cyclin D1) and 6p25 (RREB1), and loss in 6q23 (MYB). Cyclin D1 amplification is associated with poor prognosis in melanoma.

Early diagnosis of canine ehrlichiosis favors prompt institution of treatment and improves the prognosis for the animal, since this disease causes mortality among dogs. Studies have shown that determining the concentration of acute-phase proteins (APPs) may contribute towards early detection of disease and aid in predicting the prognosis. This study aimed to evaluate the APP profile in dogs experimentally infected with Ehrlichia canis, at the start of the infection and after treatment. It also investigated whether any correlation between APP levels and the clinical and laboratory alterations over the course of the disease would be possible. The results obtained showed abnormal levels of all the APPs on the third day after infection (D3), with the highest levels being reached on D18, with the exception of ceruloplasmin and acid glycoprotein, which presented their peaks on D6 and D12 respectively. We concluded that assessment of APP levels could contribute towards establishing an early diagnosis of canine ehrlichiosis, particularly regarding acid glycoprotein and ceruloplasmin, since these proteins were detected at increased levels even before the onset of clinical and laboratory findings of the disease.
